Elaborately programmed silver nanowire arrays can be prepared using a tapered push–pull nozzle system (TPPNS), which is used to directly write micro–nano wires on a substrate via a two-reagent reaction in the diffusion mixing region. The wires could be precisely positioned on the substrate and their width could be freely controlled from the micro to the nano scale, indicating an advance in the methodologies of controlling and fabricating nanowires. The as-prepared silver three-electrode device can serve as a three-electrode sensor.

使用锥形推挽式喷嘴系统制作的精心编程的纳米线

可以使用锥形推挽喷嘴系统（TPPNS）来制备精心编程的银纳米线阵列，该系统用于通过扩散混合区域中的两试剂反应将微纳米线直接写在基板上。可以将导线精确地定位在基板上，并且可以从微米到纳米尺度自由地控制其宽度，这表明控制和制造纳米线的方法学的进步。所制备的银三电极装置可以用作三电极传感器。
